Quick Start
The steps in this chapter can be followed to quickly prepare the TPA311 MSOP
audio amplifier EVM for use. Using the TPA311 MSOP EVM with the TI
plug-n-play audio amplifier evaluation platform is a quick and easy way to
connect power, signal and control inputs, and signal outputs to the EVM using
standard connectors. However, the audio amplifier evaluation module can be
used stand-alone by making connections directly to the module pins, and can
be wired directly into existing circuits or equipment.
The platform switch and jumper settings shown in Table 2–1 are typical for the
TPA311 MSOP EVM and will cause the TPA311 IC to switch to single-ended
output mode when a plug is inserted into platform headphone jack J10.
